AC power supply voltage.
Otherwise, it may cause fire or injury
• Do not perform withstand voltage test on the inverter. It may
damage the semi-conductor element.
• When wiring other devices read their manuals carefully. Samsung
is not responsible for any accident resulting from user’s
carelessness.
If not, it may cause injury or fire.
• Do not connect electromagnetic switches or contactors to the
output circuits.
• Never connect an AC power supply to output terminals U/T1,
V/T2, and W/T3.
Otherwise, it may damage the internal circuits of the inverter.
• Never short or ground output terminals: the output terminals
should not be touched with bare hands and also, the output wires
should not have contact with the inverter case
Otherwise, an electric shock or grounding may occur
• Do not connect a phase advancing capacitor or LC/RC noise filter
to an output circuit.
Otherwise, it may damage the inverter or cause a fire.
• Do not connect an electromagnetic switch or MC to an output
circuit.
Otherwise, it will actuate the over current protective circuit in the
inverter.
• Do not disassemble the digital operator.
Otherwise, it may cause a personal injury.
!
CAUTION
• Set the appropriate parameter. If not, it will not operate or trigger
the protection operation.
• Record the previous parameters (even though Moscon-E7 records
the information of the last parameter), the records can be useful
in case of malfunction or errors.
• When changing the parameters, make small change at a time
especially when controlling the motor parameter, changing the
V/f or max. output frequency. If not, it may damage the
inverter and motor.
Safety precautions

MOSCON E-7 User’s Manual
!
CAUTION
DANGER
• Do not touch the COMOS IC in the control board directly.
Otherwise it can be damaged by static electricity.
• Do not remove the digital operator from the unit since it carries
high voltages. Using the cable between operator and unit is also
prohibited, since it is very dangerous.
• Do not change the wiring, or remove the digital operator or
connectors, during operation.
Otherwise, it may cause a personal injury.
!
• Do not touch the terminals since some of them carry high
voltages and are extremely dangerous.
Otherwise, it may cause an electric shock.
• Do not remove the cover when power is being supplied to the
inverter. Always turn off the power to the inverter through the
MCCB when detaching the cover.
Otherwise, the charge remained in the capacitor may cause an
electric shock.
• After turning off the main circuit power supply, wait for a while
before maintenance or inspection since it may remain charged.
Otherwise, it may cause an electric shock.
• Maintenance, inspection, and replacement of parts must be done
only by authorized personnel.

To maintain the optimum condition, the inverter should be installed at
the ambient temperature of –10℃~40℃. If installed in a closed
environment (e.g. enclosed panel), install a cooling fan or air conditioner
to avoid any extreme temperature increases and to maintain the internal
air temperature within the range.
Install the inverter on a vertical surface to enhance the cooling effect.
When installing the inverter, always leave enough space around it to
provide normal heat dissipation.

circuit breaker
Large inrush current flows when power is supplied thus,
use appropriate breaker, which is tolerant to high
frequency.
Magnetic contactor
Installed to remote control the supply/block of the
power. Frequent start/stop of the inverter through this
device reduces durability of the inverter. Install the
surge absorber on the coil.
AC/DC reactor for power factor improvement
AC/DC reactor is required when improving the power
factor or when the inverter is connected to a largecapacity power transformer whose capacity is 600kVA or
more. If not, invert may be damaged.
Input noise filter
Install it close to the inverter to reduce the noise from the
wire.
Input wiring
Inappropriate wiring damages the inverter. Do not
connect input power R, S, and T to output U/T1, V/T2,
and W/T3. Keep enough distance between the control
signal line and main circuit to prevent the effect of noise.
Installation area
Install in a place free from gas and dust. Maintain the
ambient temperature within the specified range.
Output noise filter
Install the output noise filter close to the inverter to
reduce the noise from output wire of the inverter.
Motor
Follow the specification when running the motor.
Grounding
Ground the inverter and motor to prevent any electric
shock.
Wiring between the inverter and motor
Keep the wire between the inverter and motor short.
If not, it may decrease the carrier frequency.
Leakage current from the cable affects the inverter and
other peripheral devices.
Figure 3.4 Peripheral devices
3.6.1.1 Installing a molded-case circuit breaker
• Always connect the input power terminals (R/L1, S/L2 and T/L3) via
an appropriate MCCB.
• Large inrush current flows when power-up, thus, use appropriate
breaker. Use the one that is tolerant to high frequency.
• MCCB with a capacity of 1.5 to 2 times greater than the rated current
of the inverter should be used.
• When one MCCB is used for more than one device (e.g. inverter), the
sequence must be set up so that the power supply is turned off by a
fault output.
3.6.1.2 Installing a magnetic contactor (MC)
• The inverter is able to use without the magnetic contactor of power
supply side.
• In case of installing the magnetic contactor to input power supply in
order to prevent an accident occurred by the automatic restart
operation after the recovery from a power interruption, frequent
start/stop of the inverter through this device reduces durability of the
inverter.
• When the digital operator is used, unless the inverter operation mode is
set to the automatic start operation, it cannot be automatically started
after the recovery rom a power interruption.
• Install the surge absorber on the coil.

3.6.3 Dealing with inductive noises
3.6.2.1 Precautions when wiring on the output side of main circuit
• As mentioned previously, noise filter can be used to prevent the
inductive noise generated on the output side.
• As an option, cables can be routed through a grounded metal pipe to
prevent inductive noise.
• If the metal pipe and the signal line are at least 30cm apart, the
inductive noise can be considerably reduced.
!
DANGER
• Never connect a power supply to output terminals U/T1, V/T2,
and W/T3.
Otherwise, it may damage the internal circuits of the inverter.
• Never short or ground output terminals.
• The output wires should not have contact with the inverter heatsink.
• Do not connect a phase advancing capacitor or LC/RC noise
filter to an output circuit.
Otherwise, it may damage the inverter or cause a fire.
• Do not connect an electromagnetic switch or MC to an output
circuit.
Otherwise, it will actuate the overcurrent protection circuit of the
inverter.
3.6.2.2 Connecting the inverter and motor
• Connect output terminals U/T1, V/T2, and W/T3 to motor wires U, V,
and W respectively.
• Check if the motor rotates in correct direction according to the
command. If not (motor rotating in reverse with the forward run
command), switch any of two output terminals to each other and
reconnected them.
3.6.2.3 Installing a noise filter on the output side

3.6.5 Cable length between inverter and motor
• If the cable between the inverter and motor is long and the carrier
frequency is high, high-frequency current is leaked from the cable and
peripheral devices. This may damage the inverter and peripheral
devices.
• Adjust the carrier frequency as shown in table below.
• To change the setting related to the carrier frequency, refer to the

• C0.01 can be set to one of the following:
- One of 15 preset patterns (settings 0~14)
- A user-programmable pattern (setting 15)
• C0.01 is not changed by initialization (set B1.01= ‘1010’ or ‘1111’).
However, if C0.01=15, C0.02~C0.08 are changed to the values
associated with the case “C0.01=1” by initialization.
• If C0.01=15, the arbitrary V/f pattern can be generated by properly
setting the values in C0.02~C0.08 as shown in Fig 5.14.
• Normally high starting torque is not necessary except the following
cases:
- Long wiring
- Large voltage drop when started
- AC reactor is connected to the input/output of the
inverter
- Running with a motor smaller than the maximum
applicable motor.
- Needs large starting torque (like as in elevator)
• When using preset V/F patterns, consider the rated voltage &
frequency of the motor and load characteristics as shown in the
following table.

Function
Reverse jog command: Runs clockwise at the jog frequency.
Forward jog command: Runs counterclockwise at the jog frequency.
• Forward and reverse jog commands have priority over other frequency
commands (e.g. F0.01~F0.08).
• Do not turn on both the forward and reverse jog command.
If the setting 7 and 8 are both ON for more than 500ms, then the
inverter will stop with the stopping method set in B0.03.
• It is not necessary to input the forward/reverse run command since
these jog command alone can operate the inverter.
• These functions run/stop immediately when set on ON/OFF.
At this time, the accel/decel is not applied.

• The upper and lower limits for the output frequency with the up/down
commands are as follows:
- Upper limit=Max. output frequency(C0.02)×High speed limit(F1.01)/100
- Lower limit=Max. output frequency(C0.02)×Low speed limit(F1.02)/100
• If a run command is input, the output frequency will be accelerated to
the lower limit when this function is used.
• If the up/down function is set, the multi-step commands 1 to 8 are
disabled.

• P0.03 can be used to set the motor protection characteristic.
• Induction motors (i.e. general-purpose motor and inverter motor) are
classified based on their cooling capabilities thus, the motor overload
function operates differently between them.
* General-purpose motor : When the motor is rotating at a low speed,
the motor’s temperature rises faster than the inverter motor,
therefore torque must be limited to protect the motor from
overheating.
* Inverter motor : Motor’s temperature rise relatively slower if it is
rotating at a low speed, therefore electronic thermal overload
protection is not activated. Thus, use an inverter motor for
continuous operation at low speed.

• P2.06 can be used to set the stall prevention level during running
• This setting is valid when P2.05 =1 or 2
• Normally it isn’t necessary to change this setting.
• Decrease this setting when:
- The motor capacity is small compared to the inverter capacity
- Stall occurs when the motor is operated with the factory setting
• Set this value as a percentage of the inverter’ s rated current
(i.e. 100% corresponds to the inverter’s rated current)

‡
NOTE
• The inverter may be damaged when using the fault retry function
too frequently.
• Since the inverter might be damaged, be sure to take the following
precautions:
- Always set up a molded-case circuit breaker
- Set up a sequence that will stop peripheral equipment when an
inverter fault occurs
• The fault retry function is effective with the following faults.
With others, the protective operation will engage immediately without
attempting to restart operation:
- overcurrent
- motor overload
- inverter overload
- main circuit overvoltage
- main circuit undervoltage
•The counter which counts the number of the past fault is cleared when:
-normal operation is maintained for 10 minutes.
-the fault reset input from digital operator or input terminal is
received after the protection operation.
-the input power supply is off.

For the optimal performance of the dynamic brake, mount it in a place,
which satisfies the conditions listed below.
- Refer to the figure 1 for the dimensions and installation space.
- A dynamic brake and braking resistor generate heat, thus install the
peripheral devices, which are not tolerant to heat, far away from
them.
- Refer to the figure 1 for the mounting method.

1) Controlling the braking start voltage
The dynamic brake is related to the braking start voltage.
Refer to the Table 1. When setting the braking start voltage.
BRAKE : Braking indicating LED
FAULT : Fault indicating LED
B2 : Connect to braking resistor
B1 : Connect to braking resistor
P : Connect to P/B of inverter
N : Connect to N of inverter

3. Wiring
1) Precaution when wiring the signal line
The dynamic brake and braking resistor may generate strong noise,
thus wire separately the signal lines, which are not tolerant to noise.
The voltage-selection switch, 4P DIP SW., is located on the front of the
dynamic brake. Turn on only one of the switch corresponding to desired
braking start voltage, and turn off the rest of them.
2) Wiring method and distance
Follow the wiring methods and distances of the dynamic brake,
Braking resistor and inverter as shown on the figure 3.

5. Operation
1) Check if the required braking characteristic can be obtained.
2) Dynamic brake is operated when the inverter is starting to decelerate
and the BRAKE LED (yellow) is ON at this time.
3) If the FAULT LED is ON, 1) braking resistance is higher than the
rated value, or 2) output wire short occurred, or 3) the error has
occurred in the braking unit.
Check the problem before restarting.
Note: High voltages in the dynamic brake may cause electric shock.
Be sure to keep the cover closed when operating.
